Trimline lists five considerations of successful ship refit

With almost 53 years in business, Trimline’s experience in the marine interior refurbishment market has taught them about the key principles for refit success. They share with us their Top 5 considerations when selecting an interior contractor.

  1. Are they a trusted partner?

When selecting a contractor to undertake the interior refit of your vessel it’s vital to choose a company you can trust, with an excellent track record of delivering success. Anything can happen on a refit, so to reduce risk it is important to select a contractor with a strong heritage, who over the years have worked on a diverse array of complex and demanding projects, and are able to apply their experience gained to craft innovative solutions for your refit.

  1. Have they planned for success?

Planning for success means running a tight ship on dry land as well as onboard. From the Project Managers and Designers to the Resource experts and Foremen, every member of the contractor’s team must be experienced in, and dedicated to, creating world-class interiors. Further assurance is needed that their Logistics team are experienced in ensuring all items required for the project are delivered to site in a timely manner and that they have a ready supply of resource to deliver a quality output.

  1. Will they keep you informed throughout the whole process?

A close collaboration between the contractor and client is instrumental in delivering an end result that exceeds your expectations. By having an open and honest relationship with your contractor from concept to conclusion, you are assured that any issues are presented and that solutions are found, in a timely manner.

  1. Can you rely on them to do a first-class job on time?

By checking out the contractor’s previous work and what their other clients say about them, you can judge if they can be trusted to provide the highest quality work and results. A contractor that takes care of every part of the process and prides themselves on many long- lasting partnerships formed over the years is a testament to their guaranteed reliability.

  1. Are quality standards central to everything they do?

No matter how complex and demanding the project is, the quality of the Project Managers, Designers and manufacturing centre should be monitored at every stage to give assurance that they are working to the highest industry standards, coupled with a passion for perfection at the heart of everything they do.



Roxtec non-weld metal pipe seal now certified for use in aluminum structures 

Further scope has been added to the Roxtec SPM seal: the non-weld metal pipe sealing solution is now certified for use in aluminum structures.

The Roxtec SPM seal has received a warm welcome from shipyards, designers and engineers as it ensures safety and operational reliability, without any downtime or cost normally associated with welding. It seals and protects to A-Class standards, steel, stainless steel and copper pipe penetrations against fire, gas and water onboard marine vessels and offshore platforms.

Thanks to the new type approval certificate in respect of aluminum structures, it will not only be used in steel decks and bulkheads on large vessels and platforms, but also in yachts, catamarans, high speed ferries, fast patrol vessels and other light-weight aluminum vessels and structures.

With the ability to protect metal pipe sizes up to 222 mm in A-60 fire rated zones and provide further protection against water (1 bar) and gas (0.67 bar), typical application areas where these non-welding benefits will be utilized include lines for chilled and potable water, fire suppression systems and hydraulic fluid and lubrication lines.    

Practical protection

The Roxtec SPM seal is beneficial for shipyards who want to avoid the complex and expensive welding process and ensure certified protection where welding is either not allowed, recommended or desired.

The solution also delivers several other advantages, such as enabling users to pass the pipe material of their choice through any metal or aluminum structure without the need to change or interrupt the piping system when trying to overcome the risk of galvanic corrosion.

The Roxtec SPM seal provides installation flexibility. It is installed from only one side of the deck or bulkhead which can vary in thickness from 5 to 15 mm. Due to the in-built tolerance of the solution, it also maintains a tight seal around the pipe even when installed inside any uneven or irregular opening.

Wärtsilä Linesafe for propeller shafts revolutionises bearing design

The new Wärtsilä Linesafe brings significant improvements to the performance of intermediate shaft bearing solutions. The innovative bearing has a simplified design, which enhances flexibility and lowers lifecycle costs. The design builds on the core competencies from Wärtsilä's existing line shaft bearing solutions, long standing experience on plain bearing design and thorough understanding of the present and future customer needs of marine and oil & gas operators.

The technology group Wärtsilä launches Wärtsilä Linesafe at the Marintec China event in Shanghai in December 2017, and adds the solution to its comprehensive seals & bearings product portfolio. The simplified design of Wärtsilä Linesafe enables short lead times as well as fast spare part delivery and service response. In addition, the updated bearing design offers enhanced flexibility within the standard design, which can allow customers to select different product configurations based on their needs.

"The new Wärtsilä Linesafe is revolutionary. It's a major step forward in bearing design," says Laura Lois, Product Manager, Wärtsilä Seals & Bearings. "The Wärtsilä Linesafe is designed to address the needs of marine and offshore owners and operators. The bearing design addresses market requirements such as increased radial load capacity, allowable shaft slope as well as a reduced amount of oil necessary for operation. The modular design enables the Wärtsilä Linesafe bearing to be tailored for use in various operating environments, and in customer-specific applications."

Further operational improvements of the Wärtsilä Linesafe standard design include readiness to connect a pump when forced lubrication is required, water cooling availability, interchangeable upper and lower bearing shells, and self-aligning design. In addition, the system can be equipped with a 'safe return to port' functionality when in flooded conditions.

Simplified design with improved functionality

Wärtsilä Linesafe is a hydrodynamic bearing with a modular housing made of high quality cast iron. Its self-lubrication is enabled by a cast aluminium oil ring and oil scraper. The innovative new bearing design incorporates vast advantages offered by Wärtsilä's prior intermediate shaft bearing solutions. For instance, Wärtsilä Linesafe is fully split with the benefit of being easily replaceable and serviceable. The self-alignment of Wärtsilä's intermediate shaft bearing solution offers simple alignment and installation as well as reduced wear, resulting in longer operational life, which can help customers achieve lower lifecycle costs.

"The new Wärtsilä Linesafe for propeller shafts is suited for all vessel types from Cruise to Navy. Wärtsilä Linesafe will replace all prior variations of Wärtsilä's intermediate shaft bearing solutions," says Matthew Bignell, Sales Development Manager, Seals & Bearings. "In addition to this innovative product development, Wärtsilä provides customers with worldwide field service support and technical expertise with its global network."

NCLH enters in two-year service agreement with Scanship

Norwegian Cruise Line Holdings (NCLH) has awarded Scanship a two-year service agreement, thereby confirming the continuation of a longtime co-operation for cleaner oceans. It has been 15 years since Scanship installed the first advanced water purification (AWP) systems on the group's ships.

“We are very pleased to reinforce the technical cooperation with Scanship as a testament to our longstanding partnership and our commitment to the Environment”, says Paolo Mele, SVP Technical Operations in Norwegian Cruise Line Holdings.

Since 2002 Scanship has retrofitted eleven Norwegian Cruise Lines ships with advanced wastewater treatment systems. From 2004, six newbuilds has been equipped with Scanship’s total clean ships systems including garbage handling, foodwaste processing and bio residue treatment.

All these ships are in full compliance with the strict Alaska discharge requirements introduced in 2003. From 2010, the newbuilds in the Breakaway and Breakaway Plus class has been deployed with Scanship wastewater purification systems in compliance with the new IMO Marpol standard for special areas removing phosphorus and nitrogen.

The most recent AWP retrofit with Scanship technology was performed on Oceania Cruises' Sirena in 2016 meeting the same standard to be enforced in the Baltic Sea from 2019. In total, 17 cruise ships are today operating Scanship systems in the fleets of Norwegian Cruise Line Holding, 15 ships for Norwegian Cruise Line, one ship for Oceania Cruises and one ship of Regent Seven Seas.

“The two-year fleet-wide service agreement with Scanship includes preventive maintenance service visits, system tuning and remote monitoring for the most cost-efficient operations”, says Olivier Buton, Vice President Marine & Technical Supply Chain Management of Norwegian Cruise Line Holdings.

“Under the two-year agreement we will work with Norwegian Cruise Line to secure efficient and compliant operations by effectual provisions of service, parts, and consumables”, Bettina Nowak, Managing Director of Scanship Americas.


Wärtsilä to supply exhaust cleaning system for China built Sunstone expedition cruise ship

The Finnish technology group Wärtsilä has been contracted to supply the engines and exhaust gas cleaning systems for a 104 metre long exploration cruise vessel.

The ship is being built at the China Merchants Heavy Industry (Jiangsu) Co shipyard in China for Sunstone Ships Inc of Miami, USA. There are options for an additional nine vessels. The contract with Wärtsilä was placed by Ulstein Design and Solutions of Norway, the company responsible for delivering the design and equipment package to the yard. The order was booked in June 2017.

The full Wärtsilä scope of supply comprises two 6-cylinder Wärtsilä 20 engines fitted with the Wärtsilä NOR (NOx Reducer) exhaust gas cleaning system, and two 8-cylinder Wärtsilä 20 engines. The Wärtsilä NOR is based on SCR (Selective Catalytic Reduction) technology. The system is compliant with various NOx (Nitrogen Oxides) emission reduction needs, such as the IMO Tier III rules.

"We are delighted to be cooperating with the Ulstein company in this newbuild project. The Wärtsilä 20 engine is a very good product fit for this vessel, while the NOR system is optimised and validated for all our medium speed engines in terms of reliability, flexibility and size," says Cato Esperø, Sales Director, Wärtsilä Norway.
