The Who Dat oil and gas field is located in Mississippi Canyon (MC) blocks 503 / 504 / 547 in the Gulf of Mexico (GOM) in water depths of 945m.
Versabar is an integrated engineering company, providing a full range of services and innovative solutions for a variety of industry challenges.
The firm performs detailed engineering and design, fabrication, and system integration testing, and its trained onsite technicians operate the equipment once it is deployed to ensure successful completion of the project.
Riser and umbilical installations for the offshore industry
Versabar provides custom hydraulic winch-based systems for riser and umbilical pull-ins on jackets, spars, floating production storage and offloading (FPSO) units and semi-submersibles.
The company has installed more than 150 risers and umbilicals worldwide with loads up to 650t. For higher loads, the firm transitions to custom chain jack solutions. Versabar engineers and furnishes a complete installation system from basic functional specifications, outlining riser and umbilical weights and furnishing platform layout drawings.
Versabar’s scope of services includes detailed engineering and design of the pull-in system, equipment lay-out accounting for all platform interface issues, interfaces with the pipeline / umbilical installation contractor, fabrication of beam packages and turndown sheave support structures.
Complete system integration testing and proof loading is also supplied, along with installation and operation of the pull-in equipment.
Flex joint and stress joint replacement
Versabar provides custom engineered winch packages for application in the removal and installation of flex joints and stress joints on risers from onboard platforms without using a derrick barge and custom rigging equipment needed to support the repair operation.
Platform-based lifting solutions
Versabar’s comprehensive lifting, rigging, engineering, fabrication and operations background combined with a diverse inventory of equipment that includes rigging, winches, hydraulic jacks, air casters, skidding systems, and other specialty lifting equipment, provides Versabar with the tools necessary to handle platform-based installations, upgrades, and repairs. Versabar works with limiting design parameters, such as tight spaces, to deliver platform-based lifting systems where utilizing a crane would not be a viable solution or the use of a crane barge vessel is too expensive.
Custom hydraulic cylinder-based lifting and pulling systems
Challenged by an offshore operator to increase the storm air gap on two eight-pile Gulf of Mexico production topsides, Versabar engineered and designed a programmable logic control (PLC) deck jacking system.
The system used hydraulically and electronically synchronised rams, diesel hydraulic power units, a centralised PLC control and monitoring system, and custom engineered encapsulated leg sleeves.
Versabar’s patented deck raising system has also been successfully implemented in South East Asia to raise a multi-platform, bridge-linked complex in a simultaneous and synchronised process.
Custom manufactured hydraulic equipment
Versabar offers a wide range of custom engineered and fabricated hydraulic equipment, including:
- Hydraulic drum winches from 10t to 500t
- Hydraulic chain jacks from 400t to 1,500t
- Hydraulic traction winches up to 800t
- Level winds
- Diesel and electric-hydraulic power units
- PLC control systems
- Custom lift equipment using hydraulic cylinders
Versabar helps clients to manage risk while delivering solutions to increasingly complex projects, providing a full range of services from initial design to delivery. Based in Houston, Texas and New Orleans, Louisiana, US, the company supplies integrated solutions to customers worldwide.
With more than 30 years of experience in performing engineered lifting and pulling projects, Versabar has gained the trust and respect of major global offshore operators.

Delta House Field Development primarily involved the installation of a floating production system (FPS) at a water depth of 4,500ft in the Mississippi Canyon (MC) 254 field in the US Gulf of Mexico.
The Appomattox Deepwater Development project involves the initial development of the Appomattox and Vicksburg deepwater fields, which are located approximately 129km (80 miles) offshore Louisiana, US, at a water depth of approximately 2,195m (7,200ft).
The Lucius oil field is located in the Keathley Canyon block in the Gulf of Mexico. Anadarko Petroleum operates the field with a 35% working interest.
Mars B Project involved the installation of a new host platform named Olympus at the Mars oilfield in the Gulf of Mexico, with the aim to extend the production life of the deep-water oilfield to 2050 and beyond.
Versabar's thorough and accurate system integration testing (SIT) programme is exemplified in this test of a riser guide tube assembly (RGTA).
Versabar performed two SCR (steel catenary riser) and three umbilical pull-ins on a FPU (floating production unit) for an offshore operator.
An offshore operator recently completed steel catenary riser (SCR) FlexJoint replacements on the oil and gas export pipelines on a tension leg platform (TLP) in the Gulf of Mexico.
Versabar's VersaCutter is one of 15 new technologies to receive the Spotlight on New Technology Award for the 2015 Offshore Technology Conference.
