Utility Barge “Miss Pennie” & Multicat Support Tug “Miss. Bee”

Offshore Construction Specialists (OCS) proudly operates a versatile, purpose-built shallow water utility barge—UB-01 “Miss Pennie”—supported by the agile multicat tug “Miss. Bee.” Together, they form a highly adaptable marine construction spread, engineered to deliver integrated solutions for a wide array of nearshore and shallow to medium water depth projects.

UB-01 “Miss Pennie”

Miss Pennie was conceived, constructed, and is operated by OCS to meet the demanding requirements of modern marine construction. Based in Batam, Indonesia, the barge is designed for maximum operational flexibility, supporting everything from pipeline pre-trenching and post-trenching to small pipelay, decommissioning, and bespoke marine interventions. Its shallow draft, robust hull, and reinforced keel allow safe grounding and operations in challenging environments.

The barge features a below-deck mooring system, in-built piping, and multiple independently driven spuds, maximizing deck space and operational efficiency. Onboard, Miss Pennie is equipped with two long boom CAT 390 excavators, a 90-tonne crawler crane, a knuckle boom utility crane, and a removable stern A-frame—enabling it to handle trenching, lifting, and installation scopes with ease. The barge’s integrated power generation, air diving system, and in-house DGPS survey and management systems further support complex project requirements, while a dedicated work boat ensures seamless field support.

A standout feature is Miss Pennie’s ability to be reconfigured for a variety of operational modes, including pipelay, horizontal directional drilling (HDD) support, pipeline pre-commissioning, and even supporting decommissioning projects. The vessel’s trailing arm and jetting systems, paired with heavy-duty slurry sand pumps, enable innovative hybrid dredging and trenching solutions—demonstrated on high-profile projects across the region.

Multicat Support Tug “Miss. Bee”

Miss. Bee, is a shallow draft, twin-engine vessel (2 x 380 BHP) built for anchor handling and general support. With both bow roller and stern A-frame winching capabilities (14-tonne winch), a 25mT.m knuckle boom crane, and accommodation for up to eight personnel, Miss. Bee is the ideal companion to Miss Pennie. She ensures precise anchor deployment, maneuvering, and support for both OCS and third-party spreads, enhancing the overall efficiency and responsiveness of the marine construction system.
