AB (translated Stockholm's Helicopter Service) was established by Richard Ziverts in the late 90s, and it served as a subcontractor to HT Helikopter Transport for the first years. It obtained its own Air Operator Certificate, a national aerial work permit, in 2002.
The company started with a Hughes 269B (SE-HCM
), but its fleet was soon expanded with an MD500E (SE-JGB
In late 2004 the company added a SA 315B Lama (SE-JNA
) to its fleet. The helicopter was acquired in order to fill the need for a capable heavy-lifter in the Stockholm area since Osterman Helicopter had recently closed its regional operations.
In late 2008 the company moved to a brand new hangar in Länna, moments south of central Stockholm. By this time the fleet grown to five helicopters of four different models - Hu269, MD500, Lama and R44.
In 2010 a Bell Long Ranger (SE-HUC
) was added to the fleet.
The company was involved in extensive power line documentation tasks abroad, with projects in Poland, Finland and Norway and Italy. The operations were highly active between 2004-2013.
In May 2013 the company added an AS350B3 to its fleet and started a partnership with the sales company "Helikopterlyft". This opened up for operations in Gothenburg. The cooperation was later inherited by the sales company Osterman Helicopter, which is a subsidiary to Scandinavian Helicopter Group (SHG).
In 2013 the company placed its Hughes 269 (SE-HIN
) in Torsby, where it came to be used for census operations.
In mid 2014 Stockholms Helikoptertjänst
added power line cleansing (sawing operations) to its line of business by partnering up with the saw manufacturer Helimatic.
In October 2014 the company added a twin-engine AS355 to its fleet. The helicopter, SE-JOC
, was intended for filming and sling-load jobs in hostile environments.
In 2016 SHTAB opened a base in Orsa. The local operations were initially focused in reindeer herding and plant setting operations.
In September 2016 the sales company Osterman Helicopter changed its operating structure by switching from SHTAB to STORM Heliworks
. The AS350B3 SE-HJV
was subsequently transferred to STORM's fleet.
After terminating the cooperation with Osterman Helicopter, the newly established sales company Altin Helicopter started a tight partnership with SHTAB. Altin Helicopter is stationed in Gothenburg, and it focuses in sling load operations.
In November 2016 SHT added an AS350B3 to its fleet. The helicopter became the first aircraft in Scandinavia to get Swiss Rotor Solutions' AS350 Maximum Pilot View Kit. The kit, which had been certified recently, gives “near-Lama” visibility to Ecureuil helicopters.
In the spring of 2017 SHT went through a modernisation phase, where it sold off its R44 and an MD500, and replaced them with an EC120 (SE-JRY
). It also retired its Bell Long Ranger and the Schweizer 269.
In April the same year Stockholms Helikoptertjänst
and Hummingbird Aviation Services
opened a partnership in order to increase their redundancy as well as to facilitate commercial air transport and specialized operations for the two companies. This due to the companies' distinct focus in their respective business area. As a result of this, two EC120s (SE-JEP
) from H-bird were added to SHTAB's fleet and SHTAB's EC120 was added to H-bird's fleet.
In early 2019 Helikoptertjänst added a second AS350 (SE-JTN) to its fleet. The company's long-time workhorse Lama, SE-JNA
, was sold to Norway after 14,3 years with SHT. The AS355 had left the fleet some time earlier. By now, the company had two AS350 (one B3 and one B2) and two EC120s.
