Spar platforms are one of the most highly favoured floating platforms at the seas. Though initially these oil platform types were established only in the waters of the Gulf of Mexico as early as in the mid-1990s, in the years following technological advancements have made it possible for these equipment to be set up for operations in various other deep oceanic areas.
SPAR Offshore Platform: Technical Details
The word SPAR is an abbreviation of the ‘Single Point Anchor Reservoir’ system and refers to the constructional aspect of the spar platform design. Unlike other utilised floating platforms which generally are rectangular in shape, the spar platform is cylindrically constructed which helps it to maintain its position while carrying out the necessary oil excavation operations.
Regarded to be the most stable of oil platform types, the utilisation of spar platforms in the high seas drilling sector was a latter development in what was originally intended to be core oceanology researching usage. The stability of the platform is further enhanced because of the fact that most of its spar framework lies submerged within the water’s depths attached to the ocean floor by solid cable lines with only a small part of the platform – rectangular in nature – rising about the water’s surface.
The necessary oil excavation equipments are installed atop this raised flooring and the oil boring operations are carried from within the interior of the length of the cylindrically constructed platform specially excavated to suit the operational needs.
Parts of SPAR Platforms
The torso of a SPAR platform can be divided into four major divisions. Apart from the uppermost portion which is visible over the surface of the water, there are three other components that demarcate the entirety of the construction of the spar platforms.
Presently there are three distinct variances of spar platforms:
The conventional offshore oil platform differs from its Truss counterpart in that, the latter is slightly shorter in terms of the hull’s dimensions while its lower-end is corbelled (trussed) thus giving the offshore platform its name. Although both variances of spar platforms are cost-efficient, the Truss oil platform variances are slightly more economical as compared to the conventional floating platforms.
Cell spar oil platforms are so named because of the sextet of cylinders forming the core platform design raised above yet another cylindrically shaped base which provides better weather and tidal insulation. Thus it is made of several vertical cylinders.
The Spar platform design has become a trending matter of discussion in the maritime community. In just over 15-years since the first spar platform was installed and its operational efficiency being almost immediately tangible, there’s no denying that the concept of spar platforms has indeed been a pioneering and revolutionising initiative in the high seas’ operational domain.

The torso of a SPAR platform can be divided into four major divisions. Apart from the uppermost portion which is visible over the surface of the water, there are three other components that demarcate the entirety of the construction of the spar platforms.
- The first component provides the necessary buoyant thrust to help keep the platform raised above the water’s surface
- The middle section of the torso of the platform is where storing facilities are provided so as to store the excavated crude till they can be appropriately offloaded to the refinery facilities
- The lowermost section of the platform’s frame provides the required ballasting, thus helping the construction to be solidly moored while providing better stability especially in harsh weather and tidal conditions
