BISSO MARINE, LLC is proud to introduce the DLB BISSO IROQUOIS. Purchased in 2015, the DLB BISSO IROQUOISwas purpose built as a very stable open ocean pipelay asset capable of performing pipelay operations in diversegeographical environments.

The barge has operated worldwide and has achieved successes in currents in excess of 7 kts (3.6 m/s) andperformed continuous pipelay operations into seas greater than 10 ft (3.28 m). The operational water depthlimitation is approximately 1,000 feet, but will vary by project.

Former Names: Brown & Root / OPI: DLB BAR-323 Global Industries: DLB GLOBAL IROQUOIS

Major Performance Upgrades:

2003 – New Tensioners and A&R winch, upgraded from 270 kips (122m tons) to 440 kips (200 m tons) for major projects in the Mediterranean

2005 - Modified Alpha Pontoon stinger to “T-Bar” design and fabricated new hitch for major Gulf of Mexico projects

2008 - Repositioned helideck to bow and installed (2) section rigid truss stinger and gantry for multi-year contract for PETROBRAS in Brazil

Barge Pipelay Performance History:

Max Ø Pipe Laid: To Date - 55.5" (1.4 m) Total Ø - 48" x 1.000" wt x 3.75" CWC

Max Depth Laid: To Date - 788 ft (240 m) Depth - 30" x .750" wt x 1.75' CWC

Max Joint Weight: To Date - 34 s ton (30.8 m ton) - 42" x 1.125" wt x 4" CWC
