1. A data and power transmission inductive coupler, comprising:
- a) a U-shaped external transformer to be mounted on a stationary rig or subsea construction, said U-shaped external transformer having a coil and an inner circumferential surface;
b) an O-shaped internal transformer to be mounted on a downhole tool having a maximum tool diameter, said O-shaped internal transformer having a coil and an outer circumferential surface for mating with said inner circumferential surface of said U-shaped external transformer;
c) said outer circumferential surface of said O-shaped transformer being equal to or smaller than said inner circumferential surface of said U-shaped external transformer mating therewith;
d) said O-shaped transformer and said U-shaped transformer have no wire connection therebetween;
e) said O-shaped transformer being configured to be wired to tool electronics and batteries;
f) said U-shaped transformer being configured to be wired to surface equipment or other subsea remotely operated units; and
g) said O-shaped transformer having an outer diameter not exceeding the maximum tool diameter, and said O-shaped transformer being divided into two equal halves along said diameter for assembling said O-shaped transformer on the tool.

Abstract
A subsea data and power transmission apparatus includes primary and secondary open magnetic circuits with coils for wireless data and power transfer between a drilling tool and a drilling rig. The primary magnetic circuit is U-shaped and the secondary is O-shaped. Both magnetic systems are electrically insulated. The electrical signal and power are transferred from one magnetic circuit to another through an air or water gap between the magnetic circuits. The U-shaped and O-shaped magnetic circuits allow communication and power transfer remotely with no mechanical or electrical connectors.
