May 2009 Light weight Conference in Glasgow September 7-8.
Registration to the conference. Conference programme.
March 2009 Final reports published.
October 2008 The ship owner STENA and the Swedish Maritime Safety Inspectorate joins the LASS-C project.
June 2008 As a direct result of the co-operation between LASS and EU-project De-light Transport, DNV joins the LASS-c project where they will in particular work with the risk-analysis.
June 2008 The Swedish company CL-Special Glas AB (www.clspecialglas.se) joins LASS-c. The company is specialised in advanced glass constructions and their task within LASS-c will be to investigate possibilities of lowering the (substantial) weight of glass on the cruise vessel
May 28, 2008 A conference was held at the Kockums ship yard 28-29th of May, in the beautiful town Karlskrona on the south-east Swedish coast. The conference was a co-operation between LASS and the EU (STREP) project “De-light Transport” (www.delight-trans.net). More than 50 people attended the conference.
April 2, 2008 Co-operation between LASS and EU-project ”DE-LIGHT Transport” (www.delight-trans.net) is discussed at a meeting between the two groups at SSPA, Stockholm. LASS will take part in DE-LIGHT’s WP4A and B: lightweight design of a movable RoRo deck (aluminium or FRP-composite) and design of a cargo vessel deck house (FRP composite). The results will be compared to steel sandwich design made by DE-LIGHT.
April 4, 2008 The LASS consortium was granted additional financial support from VINNOVA for a project concerning lightweight construction of a cruise vessel, LASS-c. In the project, the superstructure will be re-designed using FRP-composite but different lightweight interior constructions will also be investigated. WP-responsible in the project will be SP, Kockums, Premec, and KTH. The technical platform of LASS is strengthened by the addition of the German ship yard Meyer Werft, that among other things to the project  contribute the case study “Norwegian Gem”, a 294 m LOA and 93 500 GT cruise vessel.

December 2007 Large scale RoPax cabin-corridoor fire test made at SP

The use of combustible lightweight materials for shipbuilding, previously prohibited by the SOLAS requirement for ”steel or equivalent” construction material, is now possible through the new (2002) Regulation 17 on ”Alternative design and arrangements”. However, the (equivalent) safety level has to be demonstrated and in this context, large scale fire experiments involving combustible composites has been made at SP in co-operation with several industries and the EU-project SAFEDOR.

Conclusions from the experiments are:

1 it is possible to obtain a high degree of fire safety in a composite construction using appropriate insulating materials,
2 a drencher is an efficient mean to control fire spread on the outside on a composite surface,
3 a RoPax cabin-corridor fire using IMO accepted interior materials can be very intense and quick developing if the sprinkler system fails to operate properly.
4 it is very important for a high degree of fire safety that the installed sprinkler/water mist systems functions properly and that air entrance to enclosures such as a cabin is inhibited, i.e. that doors are kept close.

A full report from the experiments will soon be published.

October 31, 2007 LÄSS-seminar:

Almost 150 participants from more than 10 countries attended the LASS-day at Grand Hotel in Borås October 31st. All possible aspects and interests for shipbuilding were present in the audience and it was quite clear that lightweight construction at sea is a popular topic in today’s maritime world.

A lot of information and practical shipbuilding knowledge was given during the day. Many questions from the audience concerned regulations and how authorities and classification societies approached new materials and lightweight constructions. The main opinion from “the experts” was that demonstrated examples of accepted lightweight design were needed in order to facilitate the appearance of more advanced materials for shipbuilding as the task of accepting new designs through SOLAS regulation 17 is new also to the authorities. Hopefully, LASS will be able to contribute to this.
