Mud pit cleaning
Following new environmental legislation reducing rig emissions, Gunclean Toftejorg is taking optimization of mud pit cleaning a step further through development of a simple system that allows re-circulation of water, chemicals, and mud. Only a minimal volume of water is required to initiate the cleaning process. Once sufficient volume is in the pit, the water supply can be turned off while the existing water and mud are scavenged from the pit floor and recirculated through a filter.
Offshore living quarters
The accommodation module supplied recently by Emtunga for the Cakerawala platform offshore Thailand.
Emtunga International, with 25 years' experience in the offshore sector, continues to broaden its markets. North Sea standard living quarters are now requested throughout the world, the company claims, to improve the quality, safety and general living standards for offshore crews. Furthermore, operators of floating installations such as FPSOs and FSOs no longer accept marine-standard deckhouses. With planned lifespans of 30-40 years, and 10 years between each drydocking, it is essential to have living quarters of the highest standard and with low life cycle costs.

Mechanical oil, gas seals
In centrifugal and screw pumps for multiphase, crude oil, and seawater applications, the mechanical seals often constitute a bottleneck. In subsea settings in particular, the costs of a seal brake can be high. Huhnseal has developed a series of high performance seals for these types of applications, some of which now have over 50,000 running hours. To improve the performance and running life further, the company has developed, over the past five years, a diamond coating on seal faces.
Largest hydraulic motor
Integrated Drives Sweden has developed a module-based hydraulic motor with an almost limitless torque range. The motor is intended for applications where very large torque is required such as turning of turrets, winches or cable drums. As the system is built up through use of standardized stocked components, it provides a cost-effective alternative to open gear drives. The motor will be offered with torque from 2,000,000 Nm (1,480,000 lb-ft) and upwards.
Tempered eyewash water
Krusman has developed a unique blending system for eyewashes that is equipped with a safe thermostat to eliminate the risk of scalding. This is important when there is a need to prolong the flushing time in cases where the victim has been exposed to splashes of corrosive substances that may attack the eyes or skin. If only cold water is accessible, it may be difficult for the victim to endure the required flushing time.
HIP manufacturing techniques
Metso Powdermet has won major challenging contracts from the offshore industry in recent years. Its near net shape, HIP-ed products are supplied from the world's largest hot isostatic processing (HIP) facility, located in Surahammar, Sweden.
