Ashtead Technology training academy launched

A first-of-its-kind subsea training academy was launched in Aberdeen in the world-renowned subsea centre of excellence at Westhill.

The subsea technology training academy was created to meet global demand for improved competency in the configuration, operation and maintenance of increasingly sophisticated equipment required in more complex subsea oil and gas projects in deeper waters and hostile locations around the world.

The courses available cover the basics and the more complex functioning of offshore survey equipment, acoustic positioning and motion sensing systems, hydrographic and geophysical survey equipment, cable and pipe detection and tracking systems and ROV sensors and multiplexers.

Ashtead Technology became the first subsea services company to be accredited by the United Kingdom Accreditation Service (UKAS)

This official seal of approval from UKAS demonstrates that Ashtead Technology delivers professional and technically competent calibration of survey, positioning and oceanographic sensors crucial to their customers’ subsea operations.

UKAS assesses a laboratory’s calibration and measurement capability to produce precise and accurate test results by scrutinising the technical competence of staff, the validity of the test methods, and equipment used through a vigorous audit and validation process.

Buckthorn Partners, Arab Petroleum Investments Corporation (APICORP) and Souter Investments acquired Ashtead Technology

The undisclosed funding package from Buckthorn a London-based investment firm, and APICORP a financial institution established by the ten-member countries of the Organisation of Arab Petroleum Exporting Countries and Souter Investments, allows Ashtead Technology to further expand its service offering through both organic and acquisition lead growth. The investment also enables Ashtead Technology to expand its geographical reach, with the Middle East being a particular area of interest and focus for the company.

Ashtead Technology acquires Technical Equipment Services (TES), Abu Dhabi

Since being appointed in 2012 as agents to Ashtead Technology in the Middle East, Ashtead Technology acquired TES in December 2016.

The deal allowed Ashtead Technology to roll-out its full service offering to clients in the region.

Over the past 28 years it has developed a suite of pioneering technologies and services to mitigate failure, prevent damage, and manage the ongoing integrity of offshore operations through a risk-based approach to asset integrity.

By bringing together two world-class portfolios, the deal strengthened the group’s subsea inspection capabilities, creating a wider, more competitive offering, whilst reinforcing Ashtead’s position as a leader in the provision of advanced offshore equipment solutions.

The acquisition significantly strengthened Ashtead Technology’s ROV and mechanical tooling offering, broadening its already well-established survey sensor rental fleet. It also sees the firm’s specialist subsea services capability extended with the introduction of subsea cutting equipment.

Buckthorn Partners and APICORP increase investment in Ashtead Technology

Forum Energy Technologies (FET) sold its interest in Ashtead Technology which it acquired in January 2018 as part of the transaction which resulted in a merger between FET’s subsea rentals business and Ashtead.
