This article describes a combined UV-photometer and fluorimeter constructed from 3 LEDs and a few wires, all held in place with Lego bricks. The instrument has a flexible design. In its simplest version, two UV-LEDs (355 nm) are used as light source

This article describes how to construct a simple, inexpensive, and flexible UV-photometer using one LED (355 nm) as the light source and another (355 nm) as the detector, one resistor, some wiring, a few Lego bricks, and a millivolt meter. The photom

The RFJ has been found to respond as expected, reducing well-head moments in line with the maximum predicted from global analysis simulations conducted beforehand and for all conditions experienced, i.e. for wave conditions varying from 1.3 – 6.5 m

Over the last 10 years Statoil has developed subsea remote hot tap technology. The first use of the remote hot tap technology was the Tampen Link hot tap in 2008. The hot tap cutting operation itself was performed without the use of divers; however,

Severe Microbiologically Induced Corrosion (MIC) has been discovered in several offshore pipelines, and in particular in water injection pipelines. The corrosion is characterised by long axial channels around the 6 o’clock position. The channelling

At the Asgard field a leak on a 10″ , 13Cr production pipeline was discovered in December 2000 during pressure testing. The cause was a crack at an anode pad fillet weld (pads are connectors for the cathodic protection system). Later, a similar lea

This paper deals with clump weights, a new type of component in bottom trawl gear that needs to be considered in design and reassessment of pipelines. In recent years it has become popular to use two trawl bags, a so-called twin trawl, to increase th

Steel or titanium catenary type risers may provide cost effective alternatives to flexible risers, particularly for deeper water (>300 meters). Existing analysis tools for riser response have proven reliable for most types of risers. However, in the
