TOTE Maritime’s Marlin-Class, LNG-Powered containerships are the first LNG fueled containerships in the world. Measuring 765 feet in length, 106 feet in beam and with a draft of 34 feet, the vessels are capable of operating at 22 knots. The ships were designed by DSEC, a subsidiary of Daewoo Shipbuilding & Marine Engineering (DSME), and feature DSME’s patented LNG fuel-gas system and the world’s first MAN ME-GI dual fuel slow speed engine. This will allow the ship to operate on either fuel oil (diesel) or natural gas (LNG).

Pre-Construction/Design Build Services, Marine Insulation
In September of 2013, PCI began working with General Dynamics NASSCO in reviewing DSEC’s design and construction of the TOTE Marlin Class ships. The design of a first vessel of any class is always a challenge, especially with the introduction of a cryogenic fuel such as LNG. PCI was able to assist NASSCO in working through significant increases in fire insulation requirements necessary to provide safe and effective protection for the ships.
Many of these requirements increased the insulation’s exposure to the weather. PCI identified ULVA Shield—a non-metallic cladding—as the best solution for protecting the insulation from the harsh marine environment. The team worked with NASSCO to successfully engineer ULVA Shield into the specifications in lieu of metal cladding. ULVA Shield is not only a superior product functionally, but is considerably less expensive to install than metal cladding. NASSCO delivered the first vessel in October 2015 and the second vessel in January of 2016.
