The FPSO in question is a single-hull vessel originally built in 1981 and later converted into a disconnectable FPSO in 2008. It is classed by Lloyd’s Register and has operated under a periodic inspection regime since its conversion, with a dry dock Special Survey 8...
A primary objective was to assess areas expected to become dead legs as a result of future pipework rearrangements. These dead legs, along with the commingling point for flow back to Nyhamna, have been assessed as susceptible to Flow-Assisted Corrosion (FAC),...
A leading offshore operator in the South China Sea relies on a network of subsea pipelines and flowlines to transport oil and gas from wells to its production facilities. Over the years, these pipelines have been at risk of saltwater corrosion, mechanical stress, and...
Introduction TSC Subsea was approached by a long-standing client, DeepOcean, acting on behalf of Repsol Norge AS, to conduct a diver-less, ROV-deployed inspection of multiple subsea pipe bends and T-sections of varying diameters. The inspection was to take place in...
Introduction In the deep waters off the coast of Angola, a major offshore operator faced a significant flow assurance issue with one of its 12-inch gas gathering flowlines. The suspected culprit? Hydrate plug. Hydrate formation is a major flow assurance concern for...
The Archon Gabriel Bulk Carrier was navigating the cold waters of the Gulf of Finland. The harsh sea conditions, laden with sea ice, posed significant navigational challenges and resulted in the ship’s 6-meter diameter bronze propeller suffering ice damage. Given the...
FPSO operators are increasingly seeking ways to inspect their hulls below the waterline without resorting to drydocking, a costly process that entails significant production loss, rendering it inefficient and logistically challenging. Recognising the benefits of a...
The Challenge bp sought a comprehensive, circumferential 360-degree scan of the riser. TSC Subsea provided the solution - a robotic system that could both travel longitudinally along the riser and had the ability to precisely stop and stabilise itself, in order to...
The anchor was discovered during a pipeline jet trenching campaign using a multi-beam sonar system, producing a 3D image of the pipeline and the abandoned anchor on the ocean bed. Although the area was marked as a no-anchor zone, prohibiting vessels from...
The Challenge TSC Subsea received a request from Ocean Infinity on behalf of Orsted, a Danish multinational energy company, to perform a comprehensive Flooded Member Detection (FMD) inspection on a Riser Caisson. The purpose of the caisson inspection was to ascertain...
The combination of ACFM (Alternating Current Field Measurement) technology and the MagCrawler offers a cost-effective, efficient, and reliable solution for inspecting critical welds on offshore jack-up drilling rig spudcan connections. This approach helps ensure the safety and uninterrupted operations of the client’s valuable asset.
Grout integrity verification of subsea structures is now possible thanks to TSC Subsea’s innovative technology and the development of its unique solution, the ART GUIDE scanner.
