Next Step for Island Offshore: Riserless Heavy Well Intervention
. Specialized drilling procedures allowed unconsolidated sand and shale formations to be drilled safely without any major issues,” says Manager for Top Hole Drilling and P&A Activities in Island Offshore, Per Buset. To use a rig for pilot hole drilling is much more costly than using a mobile offshore unit like the Island Constructor. Due to less manning and lower capital expenditure for “smaller” size well intervention vessels compared to a drilling rig, a lower daily rate for the riser-less coil tubing operation can be offered to the market. This will apply both for heavy intervention
Zentech Inks Deal for Two Z-210 with CSSC
Zentech Incorporated of Houston, Texas, USA signed contracts with CSSC Huangpu Wenchong Shipbuilding Company Limited for the construction of (2) Z-210 Mobile Offshore Units. These contracts were finalized based on the Letter of Intent received by CSSC Huangpu Wenchong Shipyard on September 23,2015. The Z-210 is a self-propelled, self-elevating, DP-2 capable, ABS Class, high temperature (55 deg Celsius) rated 4-legged mobile offshore unit capable of operating in water depths of up to 280 feet. The wide array of unique and innovative features of the Z-210 has already captured the attention of
Island Offshore Debuts Open Water Coil Tubing
actual drilling of the production wells. Shallow gas can be described as hidden gas pockets encountered at a depth close to the surface or mudline which can lead to blowout in the early stages of drilling. “To use a rig for pilot hole drilling is much more costly than using a mobile offshore unit like the Island Constructor. Should one come across gas and the hole needs to be plugged, it will imply large costs to move the rig to a new location for a possible new pilot hole. The risk involved with using a rig compared to a vessel is also considerable as it will need far more time to
GIMF Completes Construction of New Liftboat, The Bellator
Gulf Island Marine Fabricators (GIMF) has just completed construction of a new liftboat, The Bellator, for C.S. Liftboats, Inc, Abbeville, La.

The new liftboat features three 300-foot legs with a working depth of 235 feet and a maximum deck elevation of 282 feet above the mud line. The Bellator has 9,600 square feet of cargo deck space, a RAM 250-ton crane with a 130-foot boom and a RAM
LR Launches Offshore Drilling Software, ISIS
and manageable software requires a standardised development process, a strict, accurate yet practical testing method, and the right system from software specification at design phase to software change management at operation phase.” The ISIS notation, which is part of the newly released Mobile Offshore Unit (MOU) Rules, provides a perspective of ‘Total System through Life in Context’, and reduces the risk of ambiguity on roles and responsibilities of stakeholders - owners, operators, shipyards, and suppliers - when dealing with software and integrated systems. It improves the visibility
OTC Approves New Construction Rules
new Rule-sets approved at the first Offshore Technical Committee (OTC) held at LR's Global Technology Centre in Singapore. Lloyd's Register say that these two new rule-sets will be made public later this month (May 2013). The Floating Offshore Installations at a Fixed Location 2013 Rules and the Mobile Offshore Unit 2013 Rules, contain several changes from previous versions in order to improve usability, reflect industry best practice, new novel designs and legislative changes. The Rules never stand still and are continuously amended to improve usability, reflect industry best practice, new novel designs
