Lack of documentation and control of Specially Designed Lifting Accessories (SDLA) in drilling areas has been a recurring issue in the industry since regulations were introduced around 2012.
As recently reported by Ocean24, the Norwegian Petroleum Safety Authority (Havtil) once again uncovered non-compliance related to missing certifications and user manuals for offshore lifting equipment.

Kolos is among the few companies with proven expertise and experience in this field.
We provide both advisory services and hands-on support for SDLA, and regularly conduct courses in collaboration with the Norwegian Crane Technical Association (KTF) – specifically targeting Control Group D7 for specially designed lifting accessories used in well and drilling operations.
Our courses deliver theoretical and practical training in line with current regulations, including the requirements in NORSOK R-003 and Havtil’s training plan P-3.8. This is essential to ensure safe and efficient use of lifting equipment in drilling modules – an area historically linked to several serious incidents.
Today, there is no reason for companies not to prioritize compliance for SDLA equipment. Kolos is ready to assist – with expertise, inspection, and training.
Specially Designed Lifting Accessories (SDLA) are critical components for safe and efficient lifting operations in drilling and well intervention environments. These accessories include elevators, elevator links (bails), handling tools, running tools, hanger tools, lifting nipples, lifting caps, and lifting subs – all engineered to meet stringent industry standards such as NORSOK R-002, API Spec 8C, and ISO guidelines.

Why It Matters:
SDLAs are not just lifting tools—they are engineered safety solutions. With D7-certified control and rigorous compliance, operators can ensure reliable performance, minimize downtime, and maintain the highest safety standards in demanding offshore environments.
